DOOR-HANGER.

Specification of Letters Patent.

Application filed March 18, 1908.

Patented Nov. 2, 1909. serial No. 421,951. i

To all whom 'it may concern:

Be it known thatI, GEORGE T. BUDDLE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Door-Hangers, of which thefollowing is a specification.

My invention pertains particularly to improved means for hangingelevator doors. However, certain features of the invention are alsoapplicable to doors for other purposes.

My invention is illustrated in its preferred embodiment in theaccompanying drawings, in which- Figure l is a broken View in innerelevation of the open frame or wall of an elevator shaft and the doorcombined therewith in accordance with my invention; Fig. 2, a brokenvertical section taken as indicated at line 2, Fig. 4, and showing therelation of the upper part of the door, the

track and the hanger through the medium of which the door is supportedon the track; Figs. 3 and 4, vertical sectional vie-ws takenrespectively at the lines 3 and 4, Fig. 2; and Fig. 5 is a perspectiveview of one of the removable hub-sections or bushings with which thedoorsupporting wheels are equipped.

In the construction illustrated, A represents the open framework orskeleton-wall of an elevator-shaft; A1, a horizontal track carriedthereby; B, an elevator-door, and C a hanger for-the door.

The walls of the elevator-shaft A may be of any approved construction.In that illustrated, the framework has, as a part thereof, upright postsc, al, which carry laterally or inwardly projecting bosses a2 whichsupport the track A1.

The door B may be of any approved construction. As shown, it comprisesvertical marginal posts b; a top cross-bar b1; a bottom cross-bar 52,'an intermediate cross-bar b3, and vert-ical rods b4 joining saidcrossbars.

The hanger C is preferably of the form shown, comprising hanger-arms orbrackets c, 01,' a pair of rider-bars c2, c3, secured to the upperportions of said brackets on opposite sides thereof, so as to lie onopposite sides of the plane of the track A1, and peripherally-groovedwheels c4 mounted on the track A1 and having trunnions 010 whichindirect-ly support the bars c2, c3 of the hanger. The bars c2, c3, areconnected intermediately by studs c5 equipped with sleeves or rollersc6. These roller-equipped studs serve to stiffen and tie the barstogether in spaced relation. The track A1 is equipped with screws orprojections c7, cs, in the paths of the wheels, serving to limit themovement of the wheels in their extreme movements. The bars c2, c3, areprovided at their lower edges, between the studs c, with recesses c9adapted to accommodate the trunnions of the wheels in the operation ofhanging the door, or when it is desired to remove the wheels for thepurpose of renewing the trunnions or bushings of the wheels. Each wheelc4 'has trunnions 01 projecting from both sides,

and upon said trunnions are journaled hubsections or bushings c havingflanges 012 which flank the sides of the wheel and lie adjacent to theinner surfaces of the bars c2, c3. Each of the hanger-brackets c, c1,has an enlarged upper end-portion notched on its opposite sides toreceive the bars c2, c3, and has an inwardly offset lower portion behindwhich the track A1 lies. Near the lower end of the offset portions ofthe bracket is a lateral Harige C13 adapted to lie above the edge of thetop cross-bar b1 of the door, and the lower end of the bracket affords a`Harige c14 which embraces the inner surface of the bar b1. The flangec13 is connected with the upper edge of the door by screws c whichsupport the door. The bars c2, cS are connected by bolts c1G with blocksa' which are vertically movable in slots x1 in the upper portions of thebracketarms c, c1; the blocks being adjustable by means of screws x2which are secured through the walls :r3 above said slots and bear uponthe upper edges of the blocks. `When the screws are turned down, thebracket-arms c, c1, are elevated with relation to the bars c2, c3,thereby elevating the door. The upperedge of the rail is provided with arecess f1 preferably with an abrupt shoulder f2 and a curved surface f3.f

rIhe bushings c11 are preferably made of softer material than are theperipheries of the wheels, and the track and bars which are engagedrespectively by the wheel-peripheries and by the bushings, so that theprincipal wear will come upon said bushings. When necessary, the doormay be blocked up, the studs c5 may be removed, and

the wheels may be taken out byl bringing their trunnions to a positioncorresponding with the recesses c in the lower edges of the bars c2, c3.

The operation will be readily understood: The door may be moved upon itstrack in the usual way, the wheels traveling on the rail A1 and thetrunnions moving relatively to the bars c2, c3 of the door. n case ofany tendency to bind, the trunnions 010 will turn within the bushing011,' and, when necessary, the trunnions will slide with relation to thebars c2, 03, while the wheels are traveling on the rail A1.

Near one end of the rail A1, and beyond or outside the screw c7, is arecess g in the upper edge of said rail` Then the screw 07 is removed,the adjacent wheel may be removed by bringing it to the location of therecess g. In like manner, the other wheel may be removed by firstremoving the screw cs and utilizing the recess f1 to accommodate thewheel in the operation of removal.

In the event of sagging of the door, the set-screw :r2 maybe turned infarther to elevate the door.

rlhe foregoing detailed description has been given for clearness ofunderstanding only, and no undue limitation is to be understoodtherefrom.

What I regard as new, and desire to secure by Letters Patent, is-

l. The combination of a frame provided with a track, wheels mounted onsaid track and provided with projecting trunnions, removable bushings onsaid trunnions, a door equipped with hangers, and rider-bars carried bysaid hangers bearing on said bushings.

2. The combination with the framework of an elevator shaft equipped witha rail, of a door, a pair of hanger-brackets connected with said doorand equipped with riderbars provided at their lower edges with recesses,and wheels mounted on said rail and having trunnions supporting saidrider-bars between said recesses and the ends of said bars.

3. The combination with the framework of an elevator shaft, of a railcarried thereby, wheels mounted on said rail, a door provided withhangers and having rider-bars adjustably secured at their ends to saidhangers, said bars lying on opposite sides of the rail, and a recess insaid rail to permit removal of a wheel.

4. The combination with a frame-work of an elevator shaft, of a railcarried thereby and provided on its upper edge with recesses, removablescrews carried by said rail adjacent the recesses and projecting fromthe rail, a door, a pair of hanger-brackets, wheels mounted on said railand equipped with trunnions, and rider-bars connecting the upperend-portions of said brackets and supported on said trunnions.

5. The combination with the frame-work of an elevator-shaft, of a railcarried thereby, a door, a pair of hangerbrackets slotted transverselyof their upper extensions, wheels mounted on said track and equippedwith trunnions, blocks adjustably confined within said slots, rider-barsattached to said blocks and supported on the trunnions of said wheels,and screws for adjusting said blocks, for the purpose set forth.

6. The combination with the frame-work of an elevator-shaft, of a railcarried thereby, a door, a pair of hanger-brackets, wheels mounted onsaid track and equipped with trunnions, removable bushings on saidtrunnions, rider-bars adj'ustably secured to said brackets, adapted toride on said bushings and provided with a recess in their lower edgesbetween said wheels, and removable studs at opposite sides of saidrecess surrounded by sleeves and adapted to hold said track-bars inspaced relation, for the purpose set forth. l
